20 Feb Phylogenetics and Phylogenomics

Posted at 22:44h in Slider by davelunt

Much of my research takes a phylogenetic approach to biological questions. I am especially interested in very large scale analyses and tools to automate the path from sequences to annotated trees in a reproducible way. The image is Darwin's first...

20 Feb Phylogeography and DNA barcoding Gammarus species

Posted at 16:48h in Research by davelunt

With Jenny Rock, Nia Whitely, and collaborators I have investigated the phylogeography and ecological adaptation to different water temperature environments in Gammarus duebeni . This species shows divergence between freshwater and marine forms (subspecies) and its enormous lattitudinal range has interesting...

20 Feb Genetic diversity of spiny-tailed iguanas

In collaboration with Carlos Hasbun we studied the phylogenetics and genetic diversity of Mesoamerican spiny-tailed iguanas using both fresh samples and formalin preserved museum specimens. These revealed 3 major genetic groups that corresponded to the Ctenosaura flavidorsalis, C. quinquecarinata and the recently described C. oaxaca species. Photo Carlos Hasbun

Last January I made a list of (science) new year resolutions and made some predictions for the coming year. Thought I'd have a look back...

16 Jan From White to Meselson

Posted at 22:49h in Science by davelunt

One of the most talked about ideas in genetic studies of asexual reproduction has been that of extreme Allelic Sequence Divergence (ASD), often called the "Meselson effect" after Matthew Meselson who is usually credited with this idea. In obligatory asexuals...
